Fermi GRB 220620A: Global MASTER-Net observations report
Abstract
MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) started inspect of the Fermi GRB 220620A ( Fermi GBM team, GCN 32229) errorbox 13365 sec after notice time and 13402 sec after trigger time at 2022-06-20 05:15:28 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 74 deg. The sun altitude is -27.9 deg. The galactic latitude b = 28 deg., longitude l = 149 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2010828 We obtain a following upper limits.
